SELF-WINDING WATCH,

Application med November 1,- 1930, Serial No.

This invention relates to watches and more particularly to wrist watchesprovided with self-winding mechanism. In such watches, a pivotedpendulum is provided and is caused I its pathof swing overlies one endof the movement. I

An object of this invention is to anchor a watch movement of this typesecurely in an elongated case in such manner as to provide maximum freespace for the weighted portion of the pendulum to swing'in. I

According to this invention, the sidewalls of the case are provided withshoulders which engage the movement frame to hold incontact with one endof the case that end of the movement frame to which the pendulum ispivoted. The movement is thus securely anchored in the case and theendof the case 9.1- lotted to the weight portion of the pendulum isentirely unobstructed. 7 Other objects, novel features and advantages ofthis invention will be apparent from the following specification andaccompanying drawing, wherein:

Fig. 1 is a front view of an assembled watch with the cover open;

Fig. 2 is a similar view of the case with the movement removed;

Fig. 3 is a section on the line 33 of Fig. 2; and

Fig. 4 is an elevation of the movement.

The case consists of an elongated main or body portion to which ispivotally connected the cover 11 having a central aperture in which isprovided a crystal 12. The cover is also provided with rods 13 and 14 towhich are attached theends of the strap by means of which the watch issecured to the wearers arm. A flange 15 extends inwardly from the upperend of the body portion 10,.this flange being provided along the majorportion of 492,630, s a in Switzerland necemter "5, 192 9. "if

each end the flange is provided with inwardly extending lugs 16.

The movement is supported by a frame17 of proper configuration to bereceived inthe recess defined by the inner edges of the flange 15. Thelugs 16 engage shoulders 17 a provided on the frame and anchor itsecurely in position. A pendulum 18 is pivoted to the frame 17 at 19 andis provided with a Weighted head which swings in-the space providedbetween the end of the frame and the end of the watch case. obstructedthereby permitting the use of a large weight. I s

This space is entirely un-' An oblong dial 20 is supported by the frameand is provided with the usual hour numbers. The aperture in which theglass 12 is supportedis of suiiicient size thatthe numbers are allclearly visible when the cover is closed on the main portion of thewatch- It is of course apparent that various modi-' fications may bemade in the structure above described without in any way departing fromthe spirit of the invention as defined in the appended claims.

Iclaim':

1. In combination, an elongated case, a self-winding watch movementcomprising a frameof less length than the case and a winding pendulumpivoted to such frame adj acent one end thereof and extendingsubstantially lengthwise thereof, said pendulum having a weightedportion offset from the remainder overlying the other end of themovement and lugs projecting inwardly from said case into engagementwith said frame to anchor it with the first named end thereof incontactwith one end of said case.

2'. In combination, an elongated self-winding watch movement having awinding pendulum pivoted thereto adjacent one end and extendingsubstantially lengthwise thereof, said pendulum having a weightedportion offset from the remainder and'overlying the other end of saidmovement, and an-elongated case in which said movement is contained,

saidcase being provided with shoulders en- 7 gagingsaid movement toanchor it in said case with the end of the movement to which thependulum is pivoted in contact with the corresponding end of the case.

3. In combination, an elongated self-winding watch movement having awinding pendulum pivoted thereto adjacent one end and extendingsubstantially lengthwise thereof, said pendulum having a weighted ortionofi'set from the remainder and overlying the other end of said movement,and an elongated case in which said movement is received, said casebeing provided with shoulders to engage said movement to anchorit withthe first named end thereof in contact with the corresponding end of thecase.

In testimony whereof, I have signed my name to this specification.
